Problems solved by technology

[0004] On the other hand, most of the national currency patterns selected in the existing domestic and foreign identification software and hardware systems are pictures downloaded from the Internet, rather than data information from real banknote samples. Therefore, anti-counterfeiting often leads to inaccurate and detailed data information. Deformation and ambiguity will inevitably occur in the image, which will affect the accuracy of recognition

Embodiment Construction

[0031] The present invention will be further described in detail in conjunction with the accompanying drawings and embodiments.

[0032] The present invention is a static, intelligent, high-tech optical detection device for identifying the authenticity of banknotes. It uses image analysis, mechanical and electrical integration equipment and professional anti-counterfeiting software to check the printing features and anti-counterfeiting features of banknotes. Carry out optical analysis at various levels, and compare with the anti-counterfeiting features of genuine banknotes, so as to realize the identification of banknote types and the identification of genuine and counterfeit banknotes.

[0033] The hardware system of the present invention consists of:

[0034] Light source system: including infrared light source, ultraviolet light source, visible light band light source, special laser source and multi-band color filter combination;

[0035] Electrical system: including power...

Abstract

The invention discloses a two-dimensional currency automatic identification method and system, including the collector, scanner, stepping agency, control circuit, driving circuit and A / D converter.The collector samples monetary value from the surface of target test money, and transfers the sampled value to control circuit through A / D converter. The scanner gets the code block image data of the money. The control circuit transfer the data collected by the collector and scanner to the computer, issues control orders and transmits the corresponding state information according to computer's instructions. The invention can identify and distinguish between various currencies, including 18 kinds of domestic currencies in circulation of 436 copies (positive and negative), currency data and their security features, the types of currency denomination, edition, and serial numbers for automatic identification.

Description

technical field [0001] The invention relates to an automatic anti-counterfeiting method and its electronic product, in particular to a currency identification and identification method and its system. Background technique [0002] At present, the currency identification software and hardware at home and abroad are realized based on some limited technical means. They basically use magnetic signal reading, long-wave ultraviolet light emission, infrared emission reception, IR scanning and other characteristic detection methods. To complete the currency identification. However, there are currently 18 types of currencies allowed by banks in my country. Due to the characteristics of various currencies and their different anti-counterfeiting methods and characteristics, up to now, the identification software and hardware at home and abroad cannot fully meet the requirements of identification or identification. Requirements for different kinds of currencies. [0003] With the conti...
